The engine body and bevel gear unit reversing mechanism in the utility model are arranged in a box body (14) to form an integrated structure, compact in structural design and reliable in performance; the output shaft is directly connected with the motor transmission mechanism whose transmission shaft is centrally arranged so as to let the two axle shafts of the rear axle have an equal length and be stressed more uniformly.
Description
Affiliated technical field
The utility model belongs to the motorcycle engine technology, relates generally to a kind of regular three-wheeled motor vehicle engine with commutation function.
Background technique
Motor tricycle in using now, its driving mechanism adopts chain structure mostly, and structural design is comparatively simple, but does not generally have the reverse gear function.The driving mechanism that the present motor tricycle that proposes has the reverse gear function, representative has following two kinds: 1, at the middle part of chain transmission the commutator casing is set, chain structure is all adopted in its input output.2, at the engine output shaft end commutator casing is set, engine output shaft connects with the drive bevel gear of commutator, on the output shaft of commutator, be provided with two by dynamic bevel gear, setting by fork controls clutch cover and clutch cover is moved axially, make it with two by dynamic bevel gear engagement and separate, realize the forward and reverse of commutator output shaft, be connected with back axle by universal joint, transmission shaft by output shaft again.In the above structural design,, make engine output shaft and engine body often damage, influence the overall structure of driving mechanism simultaneously, have the not high problem of complex structural designs, reliability owing to directly connect commutator at engine output shaft artificially.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of regular three-wheeled motor vehicle engine with commutation function, makes its output shaft can directly be connected and have the characteristics of compact structure and reliable performance with the motorcycle driving mechanism.
The utility model is finished the technological scheme that its invention task takes: it comprises engine body and bevel gear set changement; The countershaft of engine body speed change gear group is connected by a pair of gear with the input shaft of bevel gear set changement, be symmetrical arranged two drive bevel gear on the input shaft of bevel gear set changement, being provided with between two drive bevel gear can be along the axially movable clutch cover of input shaft; And be provided with and drive the shift fork that clutch cover moves, be provided with the normal engagement of two drive bevel gear by dynamic bevel gear, engine output shaft with connected one by dynamic bevel gear, engine body and bevel gear set changement are arranged in the casing, the formation overall structure.
The regular three-wheeled motor vehicle engine that the utility model proposes with commutation function, engine body and bevel gear set changement are constituted a motor integral body, the structural design compactness, reliable performance, its output shaft directly is connected with the motor tricycle driving mechanism, the transmission shaft of driving mechanism can be provided with and make the two-semiaxle of back axle isometric between two parties, makes stressed more even.
